Dependency preservation is a crucial aspect in database normalization that ensures all functional dependencies are maintained after decomposition, allowing for the reconstruction of original data relationships without loss of information. It is essential for maintaining the integrity and consistency of the database while optimizing its structure for efficiency and performance.

Database normalization is a process used to organize a database into tables and columns to reduce data redundancy and improve data integrity. It involves dividing large tables into smaller, related tables and defining relationships between them to ensure data dependencies make sense and are logical.

Decomposition is the process of breaking down complex systems or problems into smaller, more manageable parts to simplify analysis, understanding, or problem-solving. It is a fundamental approach used across various fields, including biology, computer science, and mathematics, to enhance clarity and efficiency in addressing intricate challenges.
